I'm in Paris right now and can't test this change, but I've been
researching the DAA and there are a few international settings I can
change, so I've changed the driver in CVS so that you can specify
the operational mode.  Try "modprobe wcfxo opermode=1" if you're in most
of Europe and that should switch to CTR21 mode which slightly modifies a
few of the electrical characteristics of the DAA.

As we add modes you'll be able to see them with "modprobe wcfxo
opermode=-1" and then doing a dmesg.

Anyway all you folks that had some trouble like this try it out and let me
know if it makes any difference.
